Animation example from matplotlib.org does not work.
I'm trying to run thisexample from matplotlib.org. I downloaded the source code and ran:
sage: load('animate_decay.py')
sage: plt.savefig('foo.png')
The file, foo.png, contained an empty Cartesian plane. I also typed in the code verbatim into the Sage interpreter and had the same results. I am running Sage Version 5.5, Release Date: 2012-12-22 on Ubuntu 12.04.1 LTS. Any suggestions would be greatly appreciated!
I'm not sure the png format can handle animations. Perhaps look at the matplotlib manual ( http://x0.no/a9a7 ) to try to export to a format which can handle the animation? It seems `ani` is the variable in which the animation is stored. Sage provides its own animation interface, for some nice examples see: http://x0.no/a9aa
There is apng but I don't know if matplotlib can write apng. Also, not all browsers can display apng files.
Sage's matplotlib version is old. Perhaps this might be the reason that this doesn't work.
